IMPROVEMENT IN METALLIC -RCIOFINGS.

Th Schedui referred to in these Letters Patent and making part of thesame.

To all whom- 'it' may concern Be it known that I, GEORGE W.-BL1ss, ofSpringeld, in the county ot' Hampden and State of Massachusetts, haveinvented a new and improved Covering forltoofs; and 1 do hereby declarethat theiollowiug is a i'ull, clear, and exact description thereof,reference being had to the accompanying drawing making part of thisspecification, and to the letters of reference marked thereon, in which-Figure l is a plan View of one modification of my invention, showing itsform before it is stamped up in the die;

Figure 2 is a reversed plan ofthe same after heilig stamped;

Figure 3 is a side view of the saine;

,i Figure et is another modification, showing the forni before it isstamped up in the die;

Figure 5 is a reversed plan ofthe same after being stamped; and

Figure 6 a view ot' aportion ot' a root' covered with variousmodifications of my invention.

My invention relates to a covering for roofs, *which is intended to takethe place of common slatcs thatl are now used for that purpose; and

It consists ot' plates ot' metal, which are irst ent into proper form,and are afterward placed in a dic, by theaction ot' which the edges ofsaid plato, or a portion ot' the same at one end, are turned or stampeddown, so as to give an appearance of sutlicient thickness to the endexposed to the weather, and prevent the rain or wet from beating.underneath.

The plates being flexible, they may be bent orfitted to any form ofrooi'.

To give greater strength to the plate, if desirable, eorrugations orribs may be formed in the surface thereof, by the saine die; and at thesame time that the edges are stamped up, and may extend longitudinallyalong the plate, or diagonally vacross it, or in any other direction; orthey7 may be arranged in iigures or patterns, so that when the coveringis laid uponV the roof, the corrugations may form any desired pattern,or any desired combination ot' patterns.

'lo enable others Skilledin the art to inake and use my invention, Iwill. now proceed to describe the same.

In the drawing- A represents a dat plat-e, which may be made of anydesirable metal. iron, -being suitably flexible, and easily wrought andcut into the form shown in iig. 1, itslower cud heilig somewhat widerthan the upper' part ot" the plate, and extending down at the pointedendsay aquarter of an inch, more or less, than. the plate will be whenfinished.

The dot-ted lines c' in tig. 1 show the form oi' the I prefer iron, orgalvanized plato when iinished, and the continuous line c shows itstorni before heilig stamped up.

The plate, as shown in iig. l, is subjected tov pressure ina die, andthe surplus metal, shown by the space betweenthe dotted line c and theline o, is turned ont to nearly a perpendicular `position to the mainpart vof the plate A.

'lhat part of the plate below the dotted li'ue a shows about theproportion of the wholeY plate that is ex` posed to the weather.

A concave groove,-o, may be stamped in thesur-h faoe of the plate,extending` around the edge of that part of the plate which is exposed tothe-weather, or, instead of extending around therentire Vedge ot' theplate, two or more such grooves may extend Alongitudinally along theplate, or diagonally across it.

Any desirable pattern may be stamped upon the surface ot' the plate,which may be either "sunken or raised upon the outside.

This pattcrnwould serve to give the plate strength in the saine mannerthat strc ight eorrugations or ribs would, and the piates would presentarmuch better appearance when laid.

In iigs. 4; and 5 is represented another modifica# tion, in whichtheplate is made rectangular when finished, its form before beingstamped up being shown in iig. 4.

The space between the ldotted line c and the continuous line c shows thesurplus metal, which is turned up into a position perpendicular to themain portion of the plate, as shown clearly in ltig. 5, 'c showing theturned edge. r

rlhe last-mentioned rigs. 4 and 5 show the plate as' plain, which, forsome purposes, may vbe sufficiently strong without the ribs orcorrugations.

Figfi shows different modifications of th'eniinven` tion, laid upon aroot', and they may be differently corrugated or oruamented, so as topresent aYariet-y fof patterns upon the same root'.

`Fig. f3 shows the thickness of the platel as`it appears when iinished,the edge oi the metal, which is turned out, beingshown at c. This givesan appearance of thickness to the lower end of the plate when laid, andmakes it Astitfer than it would otherwise be, and prevents the lower'end of the plate from becoming loosened, or turned up, so as to admitthe rain or wet.

Even with any pattern .or corrugations stamped upon the plate, itSutticiently flexible to allow of its being bent to fit any curve orsurface of any roof.

This is cheaply made, as the plate may he stamped out at the same timethat the edge is turned, and the pattern or corrugations stamped uponit, the whole being made at one opera-tion oi' the die; and, if' made ofiron, the plates may be painted sutiiciently 'to prevent the iron fromrusting hy exposure to the weatherfzind the plates nailed to the roof,holes being made therein for that purpose.

Having thus described my invention,

That I claim as new, and desire to secure ters Patent, is-

An improved covering 'for roofs, consisting of metallie plates A, havingthe edges turned :tt c, :md

hv Let- Ind set forth.
